A bit less is needed here in custom.cfg:
menuentry "Debian 13 Trixie defkernel 3 on P10" {
        load_video
        set gfxpayload=keep
        search --no-floppy --set=root --hint-baremetal=ahci0,gpt10 --label zd8p10deb13
        linux /vmlinuz root=LABEL=zd8p10deb13 noresume consoleblank=0 preempt=full mitigations=off
        initrd /initrd.img
}
menuentry "Slackware 15.0 GUI on P25"{
	load_video
	set gfxpayload=keep
	search --no-floppy --set=root --hint-efi=hd0,gpt25 --label zd8p25slack
	linux /boot/vmlinuz rw root=LABEL=zd8p25slack noresume consoleblank=0 mitigations=off
	initrd /boot/initrd.gz
}
